这栋房子是这个城市新建筑的典型，因为它兼具古典和现代建筑的优点。
This house is representative of the new buildings in the city, as it has all the merits of both classic and modern architecture.

这里为什么不能用classical呢？不都是表示古典嘛？

同问，我也不知道...

貌似classic有最优秀的这层意思而classical却没有

classic：第一流的，不朽的，古典的，比如说中国的四大名著就用classic；
classical：经典的，古典文学的，指古希腊，罗马的文学、艺术，意为”古典（文学，艺术的）“。在文学上，它与romantic和popular music相对

classical多用于形容艺术和科学类,classic应用范围更广
